Specification of Letters Patent.

Patented Sept. 1a, rein.

Application filed. February 15, 1915. Serial No, 8,364.

erence being had to the accompanying drawings, forming a part of this specification.

The invention relates particularly to a method for building reinforced concrete silos, storage tanks, chimneys, bins, Walls, etc.

In this construction, concrete columns are poured at intervals, said columns tying into a wall structure which may comprise precast concrete blocks, hollow tile, brick, stone or other like material or a metal lath plastered siding. The constructing apparatus is composed of a permanent Wall member and a temporary framework comprising a superposed track or plate to which are attached depending channellike studs, preferably formed of sheet metal. This plate is curved or formedto the desired outline of the structure, the channel studs standing like legs or studs against. which the permanentfwall member or backing is built. These chan nels being properly plumbed enable the wall structure to be built up vertically, the spaces between the wall member and the bases of the channel studs are filled with slush concrete forming concrete columns, which unite with the permanent wall member to form. the finished wall structure. Vertical and horizontal reinforcement may be embedded as desired during construction.

In the drawings, Figure 1. is an isometric drawing disclosing a section of the wall building mechanism as used in construction. Fig. 2. shows a horizontal section taken. through a block wall and mechanism like that seen in the lower portion of Fig. 1. Fig. 3 shows a silo under construction. Fig. 4 represents a plan of such silo, one half showing the completed wall, the other half being a plan of the temporary wall building framework. Fig. 5.'is a fragmentary horizontal section taken through a concrete silo wall along a mortar joint. Fig. 6. is a vertical section taken along line X-X in Fig. 5. Fig. 7 is a horizontal section of a single block taken along the line Z-Z in Fig. 6.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

Referring to the drawings, in Fig. 1 is shown a guiding plate 10 such as an angle iron.- This track 10 is straight or curved and conforms to the outline of the structure to be built. On small structures a square or rectangular plate like 10 bolted together at the corners is stiff enough to retain its shape during construction, Otherwise bracing or guying may be resorted to.

Attachedto and supporting this plate 10 are seen depending channel like studs, formed preferably of sheet metal. Any fastening means may i be employed. 12 represents a bolt or pin showing one method of attachment. In Fig. 2-at 13 is shown a loop 13, fastened to the base of a channel stud 11, through this loop a pin may be driven into the foundation or base .to hold the channel stud to its place during construction, or the stud may be otherwise braced or secured. This plate and attached channel studs constitute a temporary framework ready for wall construction.

The channel studs 11 being set and plumbed and the guiding plate 10 alined,the permanent wall member is erected. Blocks t of tile, cement stone or other building material comprising this wall member are laid on the foundation, being in contact vertically with the edges 15, 15 of the channel studs 11, which act as straight edges and supports for alining superposed courses-of blocks as 14*, preferably beveled and approximately in contact at 17. These blocks l4and l4. close the channel studsll thus forming a space or column mold 18 between the base of the channel and the permanent wall member, into which space 18 slush concrete 19 is deposited which forms a concrete column.

A rod 20 laid horizontally between courses of blocks will reinforce the columns and blocks horizontally. Rods 21 placed vertically in the space 18 during pouring of columns 19 provide vertical reinforcement.

Beds 20 and 21 may be tied together by w1re or stirrups as at 22, Fig. 2. It will be understood therefore that I depend upon the guiding plate 10 to hold the channel studs 11 channel stud 11 and a permanent wall mem I ber or backing such as 14:, 1 1*.

The column mold 18 may be formed'by the channel stud 11 and a permanent wall member such as metal lath 23 held to the studs 11 by such means as removable. wire. clips 24.
